# 04-01 Summary

## Outcome

Wave 1 reconnected the native text backend as a first-class reader path inside the existing shell.

- `RDEPUBReaderController` now builds a real native snapshot from `RDEPUBTextBook` instead of leaving `activePages` / `activeChapters` empty
- Native restore and current-location resolution now go through shared controller helpers instead of scattered text-book special cases
- Native page turns update `RDEPUBReadingSession` with page/spine/chapter context, so reader state stays coherent with the visible page
- `RDReaderView` remained unchanged; it still only consumes content views and page counts

## Compatibility

- No new reader shell or page-turn container was introduced
- TXT and EPUB native text flows still use `RDEPUBReaderController` and `RDEPUBTextContentView`
- `RDEPUBTextBook` remains the backend contract for native reflowable pages
